LOCK.

SPECIFICATION forming part of Letters Patent No. 716,510, dated December23, 1902.

Application iiled April 24,1902. Serial No. 104,517. (No model.)

To all whom t may concern:

Beit known that I, ISAIAH W. WOLF, a citizen of the United States,residing at Midway, in the county of Putnam and State of West Virginia,have invented a new and useful Lock, of which the following is aspecification.

This invention relates generally to locks, and more particularly to oneintended for use upon inail bags or pouches, trunks, and the like.

The object of the invention is to provide an exceedingly cheap, simple,and compact construction of lock and one which will automatically lockthe hasp when inserted into the case and which will project the saidhasp out of the case when unlocked by the key, thereby avoiding thenecessity of pulling the hasp out by hand.

With these objects in view the invention consists in the novel featuresof construction, combination, and arrangement, all of which will befully described hereinafter, and pointed out in the claim.

In the drawings forming a part of this specification, Figure lis a Viewillustrating the exterior of the case and the key. Fig. 2 is a sectionalview illustrating the mechanism of the lock and the manner of fasteningthe hasp within the case. Fig. 3 is a transverse sectional View of thelock. Fig. 4 is a detail perspective view of the hub carrying theunlocking-cams. Fig. 5 is a detail perspective view of the springcarrying the locking-lugs. Fig. 6 is asectional View of the hasp, andFig. 7 a side View.

In carrying out my invention I employ a case which may be made of castor wrought metal and comprises an inner or base plate A, the outer ortop plate B, and the sides C, said outer or top plate B and sides Cbeing preferably formed integral. Base-plate A is considerably widerthan the outer plate and is provided with a series of perforationsthrough which rivets may be passed for the purpose of securing the caseto the bag or trunk. The side walls of the case are separated at theupper eind, said separate ends being turned inwardly, as shown at C',thereby providing a passage-way for the reception of the hasp,hereinafter described.

The U-shaped spring D is arranged within the case, the bow portion ofsaid spring being securely held in a bifurcated post E, arranged uponthe base-plate A adjacent to the lower end thereof, the free ends ofsaid spring being bent slightly outward, as indicated at D', andadapt-ed to rest against the inwardly-proj ecting passage-walls C, asmost clearly indicated in Fig. 2.

Fastening-lugs F are carried by the spring D, said lugs being preferablyintegral with the said spring and projecting toward each other, theiropposite faces being beveled, as indicated at F', so that the end of thehasp can pass easily between them. The hasp G has notches II cut in itsopposite sides adjacent to the lower end, the locking-lugs F beingadapted to engage the said notches when the hasp is passed down into thecase, as indicated in Fig. 2. The hasp G is formed with a longitudinalbore I, in which is located a spiral spring K, said spring bearing uponthe collar L of a pin L, arranged within the said bore, and projectingthe lower end of said pin beyond the lower end of the hasp.

M indicates a hub arranged upon a spindle or post M between the membersof the U- shaped spring D, said hub being provided with cam-shapedextensions N, which are adapted to engage the opposite members of theU-shaped spring and spread them apart for the purpose of disengaging thelocking lugs from the notches of the hasp whenever the hub is turned bymeans of the key I), said hub having the proper opening M2 for thepurpose of receiving the bit and barrel of the key.

If desired, a guide collar or iiange M3 may be formed upon the innerface of the plate B for the purpose of holding the hub and the spring intheir proper relative positions, such construction being illustrated inFig. 3.

A flat post O is arranged between the members of the U-shaped spring andis adapted to be engaged by the spring-actuated pin L when the hasp isinserted into the lock, and the moment the members of the lJ-Shapedsprin g are separated, so as to disengage the locking-lugs from thenotches of the hasp, the force of the spring acting upon the said ha-spwill serve to project it out from the case,

thereby avoiding the necessity of withdrawing the said hasp by hand.This post also serves as a stop to limit the inward movement of thehasp, and thereby insures the proper action of the locking-lugs carriedby the spring.

It Will thus be seen that I provide an eX- ceedingly cheap, simple, andcompact construction of lock capable of use upon mail bags or pouches,trunks, and the like.

The hasp G is provided With an ear G, which is adapted to be passedthrough a link G2, connected to the strap G3, thereby pivotallyconnecting the said hasp, so that it can be thrown back whenever it isdesired to avoid fastening the lock, as may sometimes happen-forinstanoe,when the hasp is at- 'rached to the top of the trunk.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

A lock comprising a case, the sides of Which are turned inwardly at oneend, providing a passage-Way, a U -shaped spring arranged within thecase and carrying locking-lugs at its Jfree ends, the hub havingcam-shaped projections arranged within the spring, a hasp havingoppositely-disposed side notches, and a spring-actuated pin projectingfrom the end of said hasp, and a Hat post arranged within the oase andadapted for engagement With the said spring-actuated pin for the purposeof projecting the hasp out of the case when the lock is unfastened,substantially as specified.
